It doesn’t take much for an American residing abroad to have complicated taxes. I work a salaried job and am trying to save for retirement and that puts me into the complicated bracket because of the rules on pension taxation in my country of residence vs the US. Our options for investment are very limited, compared to every other resident of the country. My local brewery was doing a grassroots investment campaign and I couldn’t even buy £20 worth of shares to support them because as a US person that was forbidden.
